Hmmm... Looks very similar to the device I got, and posted in an earlier thread. The main difference is that your device uses a wireless transmitter, whereas my device transmits its signal via the wiring inside my house. But both devices look like they are good for keeping a real-time eye on your house electrical use.

The Power meter arrived yesterday and I installed and programed it. Quite an easy installation. It's as addicting as the SG. It's a real eye opener when you see the effects of different units and the power they draw and how much an hour it costing. $2.10 for todays usage.
